Android Question B4A bridge problem

Did you uninstall/delete the previous app from your device ?

Try that and re-compile and it should work.

You are referring to the install button in the system dialog, right?

It can happen if there is an app running that can draw over other apps (screen recorder for example).

I refer to the install button of b4a bridge. Its not working, all i can do is cancel B4A bridge.
I closed all running apps and i uninstalled previous app, but still the same problem.
I am not aware of running apps like screen recorder.
It occurred after an update of Android 7 in october this year at galaxy J7 (2016) phone.
If i use B4A bridge at a Galaxy J7 (2017) there is no problem.
Also on my old tablet (about 100 B.C.) its still working.
I did not made any changes in developer options at both phones.
brrrrrrrrrrrrr

There is no install button in B4A-Bridge. You are seeing the system dialog.

You can always switch to USB debug mode.

Yes okay. In USB debug mode it works.
Maybe in WIFI there are some problems.
